I would like to claim this please.
I've been working on a cave that should fit this exterior. What do you think about making it an abandoned mine? My idea is that the beginning of the mine is still mostly intact, but farther in the infrastructure gets more and more damaged. Possibly rock falls and the general instability of the area dissuaded further mining in the deeper areas, and the beginning area ran out of ore. Also, the bridge to the deeper areas was badly damaged by a rock fall, and it wasn't worth repairing, since it was liable to break again in the near future.

Update:
Not finished yet, but it's coming along. I still need to add some more rocks in the tunnels and caverns, and start adding furniture and clutter, as well as set up the light sources. Also, I've split the claim into two cells to keep fps high and allow the player to always be able to sleep in the first area.

This is an active silver mine, and the first area will have miners in it. When the village above the mine was destroyed, the invaders(either Nords or Redguards) didn't damage the mine so they could make use of it themselves. So if it was a Hammerfell village, the miners are Nords/Skyrim citizens, and if the village was controlled by Skyrim before it was destroyed, the miners should be Redguards.

The second area of the mine is severely damaged by rockfalls, and is very unstable. The miners refuse to work in the area despite the large amount of silver ore in that section. Even if they would work there, the bridge is broken and cave-ins block the path. Rats and other vermin have taken up residence there in the miners' absence. The cave-ins are natural and unrelated to the war.

Clean: Yes
Northmarker: Set
Illegal to Sleep Here: Set in first interior, turned off after checking a couple of vanilla mines for comparison
Lighting: Good

First interior cell:
Floaters:
miner's pick - I properly rotated a bunch of these. A few were good though.
T_IngFood_FishSalmon_01 - not resting in plate
T_IngMine_OreSilver_01 - so many... too lazy...
T_Nor_WoodenPlate_02b - resting on a point on bottom, 'f'ed into table
T_SkyCom_Var_Sk3Mine - resting on a point, bled into planks, also put against a crate

Bleeders:
sky_ire_lorchw01_lantern1 - lifted up. Lights don't like being 'f'ed into place, they have to be moved down with a delta movement of 0.1 until the selection box is flickering
T_Com_Hammer_02 - bleeding into plank support
T_Com_Hammer_02 - as above
T_IngFood_Honey_01 - bleeding into bowl
T_Nor_Var_LanternStat_01 - these ones were bleeding into the poles
T_Nor_WoodenFork_02b - these were bleeding into table and not properly rotated
T_Nor_WoodenKnife_01b - as above
T_SkyCom_Var_Bl1Fish - bleeding into crate
T_SkyCom_Var_Bl1Torch - as above
T_SkyCom_Var_Sk3Mine - bleeding rather weirdly, moved to bleed into center of the crate
